THE FLIGHT The deception was meticulous. Olds's F-4s flew the same routes, altitudes, speeds, and call signs as F-105 formations. They carried QRC-160 electronic countermeasures pods previously used only on Thunderchiefs, emitting the same radar signatures. The North Vietnamese, monitoring American radio traffic and electronic emissions, took the bait. On 2 January 1967, as the F-4s orbited over North Vietnamese airfields, MiG-21s rose to intercept what they believed was a routine strike package. In the ensuing engagement, the 8th TFW—aided by the 366th TFW covering withdrawal routes—shot down seven MiG-21s (some sources cite up to nine) without losing a single American aircraft. Colonel Olds personally scored one of the kills. The North Vietnamese Air Force was grounded for months to retrain and reorganize. Olds dubbed his wing "the Wolf Pack" that day, and the name endures.
